# transform

The position and orientation of the camera in world coordinate space.

```
var transform: simd_float4x4 { get }
```

## Discussion

World coordinate space in ARKit always follows a right-handed convention, but is oriented based on the session configuration. For details, see [Understanding World Tracking](/documentation/ARKit/understanding-world-tracking).

This transform creates a local coordinate space for the camera that is constant with respect to device orientation.
In camera space, the x-axis points to the right when the device is in <doc://com.apple.documentation/documentation/UIKit/UIDeviceOrientation/landscapeLeft> orientation—that is, the x-axis always points along the long axis of the device, from the front-facing camera toward the Home button.
The y-axis points upward (with respect to <doc://com.apple.documentation/documentation/UIKit/UIDeviceOrientation/landscapeLeft> orientation), and the z-axis points away from the device on the screen side.
